So let's clear up your confusion. BSPs that are provided for PetaLinux are not Yocto BSPs, and PetaLinux does not interoperate with Yocto (in any way). PetaLinux does however use a Root Filesystem that is pre-built by Yocto. >From a functional use stand point PetaLinux has nothing to do with Yocto, and Yocto has nothing to do with PetaLinux.

In terms of Yocto support, meta-xilinx is what you are after for Xilinx architectures (including Zynq). There is board support for the ZC702 and ZC706 available (and picoZed is planned for the upcoming release).

Technically it does not matter which Zynq-7000 chip you are using as the programmable silicon is consistent across the models. It is the board that is generally configured differently, I assume you are asking this question due to the four SKUs for the picoZed (7010, 7015, 7020, 7030)?
